George Kirk, a 23rd century Starfleet officer, owned a PX70 prior to his death. His widow, Winona, told her son James that George would drive it with her seated behind him, which would drive her nuts.
In 2263, while stranded on Altamid, Jim Kirk noticed a PX70 in the Franklin's mess hall. He rode the motorcycle as a distraction while his officers rescued the former crew of the USS Enterprise from Krall's camp. To increase the confusion, several holographic replicas of himself and the vehicle were created, all headed in different directions. (Star Trek Beyond)
